Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0159/1085] net: genet: enable link energy detect powerdown for
external PHYs
There are several warts surrounding bcmgenet_mii_probe() as this
function is called from ndo_open, but it's calling registration-type
functions. The probe should be called at probe time and refactored
such that the PHY device data can be extracted to limit the scope
of this flag to Broadcom PHYs.
For now, pass this flag in as it puts our attached PHY into a low-power
state when disconnected.
